BOILER-SKIMMER.

Specification of Letters Patent. Patented June 13, 1916 Application filed March 4, 1915. Serial No. 12,013.

To all whom it may concern:

Be it known that we, NORBERT SOHREIBER and RAPHAEL RosnN'rHAL, citizens of the United States, residing at Lincoln, in the county of Logan and State of Illinois, have invented a certain new and useful Improvement in Boiler-Skimmers, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

Our invention relates to boiler skimmers or like devices, and especially to a type or construction of boiler skimmer adapted for use in locomotive boilers.

Prominent objects of the invention are to provide a simple and practical boiler skimmer arrangement by which a locomotive boiler may be efiectively skimmed, and especially to permit this to be done by a continuous discharge-or blow-off, to arrange for the control of this continuous dicharge or blowofi", to make the same greater or less as desired; to permit the unrestrained or full discharge whenever desired; to arrange to protect the apparatus from injury or meddling, and also to protect it from the weather and otherwise; to arrange for convenient access to the parts to be operated; and to secure the foregoing and other desirable results in a simple and expeditious manner.

In the accompanying drawings Figure'l is an elevation partly in section of a portion of locomotive boiler provided with a skimming apparatus embodying our present invention; Fig. 2 is a plan view of the skimming device proper; and Figs. 3 and 4 are views of details of construction.

The arrangement shown in Fig. 1 comprises a locomotive boiler 1, which may be of any usual type, a steam dome 2 being also shown. Within the boiler we show the usual dry pipe 3. We also show a throttle lever 4 arranged at the rear of the boiler and connected'with a rod 5 which is understood to be operated by said lever 4 in the usual way to open and close the throttle valve (not shown). We show also a skimming device 6 which may be of various forms or constructions, a preferred form being shown in Fig.

2. In such arrangement side pipes 7-7 are prov ded, the same having apertures 88 iormlng surface intakes. An end pipe 9 is provided, the same being elevated with reference to the lower pipe 7 and connected with the same by vertical pipes 10. Side or supplemental pipes or members 11 are provided extending lengthwise of the pipe 7 and floats 12 are shown mounted upon the supplemental pipes 11. The elevated pipe 9 fits'above the dry pipe 3. A discharge pipe 14 extends rearwardly from the skimmer 7, being connected with the same by a swivel joint 15, and also with a swivel joint 16. The end of the skimmer 7 adjacent the several connections 15 and 16 is supported upon a rod 17 extending to the dry pipe 3. A connection is shown between the throttle valve rod 5 and the skimmer by which the latter may be discharged or blown off by the operation of the throttle valve lever 4. The particular form of connection shown comprises a finger or pin 18 extending downwardly from the valve rod 5 and arranged to work in a slot 19 formed in a lever 20 (Fig. 4) connected with a valve 21 in an extension 22 of the discharge pipe 14. In this way the throttle lever 4 when operated to open the throttle valve will also operate the valve lever 19 so as to open the valve 21 and thereby permit the discharge or blow ofllof the skimmer 7, and this blow-oil? or discharge will be continuous during the time the throttle valve is open. When, however, the throttle lever 4 is operated to close the'engine throttle valve, the lever 20 will also be operated so as to close the valve 21 and thereby shut off the discharge or blow-off from the skimmer.

It will be noticed that all of the parts excepting the throttle lever 4-and the extreme end of the rod 5 connected therewith are located inside of the locomotive boiler, whereby they are protected and prevented from freezing in cold weather. A pipe 23 is connected with thevalve 21 and this pipe extends to the wall of the boiler and through the same at 24 and is then connected'with an outside drain or discharge pipe 25. This latter pipe may extend to various different positlQllS suitable for the discharge of the matter passing through the skimmer, a preferred arrangement being to locate the end of said pipe so that the discharge will be upon the track on which the engine travels in front of or in the vicinity of one or more of the driving wheels. The pipe 25 is preferably provided with a plug valve 26 shown in detail in Fig. 3. This plug valve has an orifice or bore 27 which is controlled. by an adjustable screw 28 so as tomore or less restrict the flow of the discharge passing through the member 26. There is also shown a supplemental discharge pipe 29 whichalso preferably extends down into the neighborhood of the end. of the pipe,26. This pipe 29 is provided with a globe valve 30 having a handle 31 which can be operated manually. Thus the pipe 29 may be opened wide whenever desired by operating the wheel 31 to permit a free and unrestricted blow-off of theskimming device. These pipes 25 and 29 and the valves 26 and 30 are preferably outside of the boiler so as to permit ready access to the same for adjusting the valves 26 and 30.

It will be understood that changes and modifications may be made without departing from the spirit of the invention.

In an application filed by us October 17 1914, Serial No. 867,055, boiler Skimmers, we disclose an apparatus containing certain of the features of construction and operation herein set forth and claim certain of said features in said other application.

WVhat we claim is:

l. The combination with a locomotive boiler and throttle valve, of a skimming device located within the boiler, a valve controlling the skimming device, tubular connections between the valve and the skimming device, a member supporting the controlling valve and the skimming device, and connected with the tubular connections between the valve and the skimming device, said skimming device being hingedly connected to the tubular connections between it and the controlling valve.

2. The combination with a locomotive boiler and throttle valve arrangement therefor, of a skimming device located Within the boiler and a connection between said throttle valve arrangement and the skimming device also located within the boiler, and a pair of discharge pipes for said skimming device located outside of the boiler.

3. The combination with a locomotive boiler and throttle valve arrangement therefor, of a skimming device located within the boiler and a connection between said throttle valve arrangement and the skimming device also located within the boiler, and discharge pipes for said skimming device located outside of the boiler, one of said discharge pipes being provided with a restricted orifice and means for varying the size of the same.

41. The combination with a locomotive boiler and throttle valve arrangement there for, of a skimming device located within the boiler and a connection between said throttle valve arrangement and a skimming device also located within the boiler, and discharge pipes for said skimming device located outside of the boiler, one of said discharge pipes being provided with a restricted orifice and means for varying the size of the same, and another of said discharge pipes being provided with a manually controlled Valve.
